GTK对话框构造函数不能用于创建子类Messagedialog WTF的实例

发布于 2025-02-04 05:48:31 字数 473 浏览 3 评论 0原文

当我运行以下代码时：

 dialog = Gtk.MessageDialog.new(
            None,
            Gtk.DialogFlags.MODAL,
            Gtk.MessageType.QUESTION,
            Gtk.ButtonsType.YES_NO,
            f'Do you really want to {action} "{data["list_element"].name}" ?',
        )

我会收到此错误：

Dialog constructor cannot be used to create instances of a subclass MessageDialog

这是什么意思？我该如何解决？

When I run the following code:

 dialog = Gtk.MessageDialog.new(
            None,
            Gtk.DialogFlags.MODAL,
            Gtk.MessageType.QUESTION,
            Gtk.ButtonsType.YES_NO,
            f'Do you really want to {action} "{data["list_element"].name}" ?',
        )

I get this error:

Dialog constructor cannot be used to create instances of a subclass MessageDialog

What does it mean? How do I solve it?

我认为问题是使用new，它似乎是为父gtk.dialog类保留的。来自这个来源直接使用gtk.messagedialog构造函数：

 dialog = Gtk.MessageDialog(
            None,
            Gtk.DialogFlags.MODAL,
            Gtk.MessageType.QUESTION,
            Gtk.ButtonsType.YES_NO,
            f'Do you really want to {action} "{data["list_element"].name}" ?',
        )

I think the problem is the use of new, which seems to be reserved for the parent Gtk.Dialog class. From this source, it seems you can use the Gtk.MessageDialog constructor directly:

 dialog = Gtk.MessageDialog(
            None,
            Gtk.DialogFlags.MODAL,
            Gtk.MessageType.QUESTION,
            Gtk.ButtonsType.YES_NO,
            f'Do you really want to {action} "{data["list_element"].name}" ?',
        )
